I'd like to discuss Saturdays. I love Saturdays. End of discussion.

Chocolate Topping

Ingredients

Spread melted chocolate onto eclair shells
Done!

Now for the delectable eclair filling custard.

Ingredients
4 egg yolks
1/3 cup sugar
1/4 cup flour
1 1/2 cup milk
1 tsp vanilla
1 Tbsp peanut butter (optional)

Begin at the beginning
1. In a small sauce pan, with occasional stirring, bring the 1 1/2 cups milk just to a boil* (milk will look all foamy)
2. Remove from heat and let cool a little while you attend to the next steps

Prepare the Eggins
1. Separate 4 eggs putting the yolks into a medium sized bowl
2. Whisk 1/3 cup sugar into egg yolks
3. whisk 1/4 cup flour into egg yolks

Temper
1. Whisking constantly, add about 2 Tbspns warm milk into the egg yolk mixture
2. Slowly add remaining warm milk whisking constantly

Cook it
1. Pour liquid into sauce pan
2. Stir with spoon or spatula over low-med heat until it thickens and will slightly pull away from the pan

Additions
1. Pour thickened custard into a bowl add 1 tsp vanilla and if you wish for peanut butter flavoured custard, add 1 Tbsp peanut butter and stir until it's incorporated
2. Cool it and eat it or jam it into one of your artfully prepared eclair shells. (You genius you)

*Watch your boiling milk carefully, it's like your drunk friend who insists they can drive after drinking a 12 beers and 6 shots of jager- belligerent and liable to spew all over you at any moment. Don't let either one happen.
